Leiter, Perez & Associates, Inc. completed the design, contract documents, and contract administration for a force main system improvement in Southwest Dade County. About 1,500 feet of 16 inch diameter force main was installed next to an existing 12 inch force main to eliminate a bottleneck. It was necessary to jack and bore a 30 inch casing pipe under the Palmetto Expressway at the Snapper Creek canal. Permitting was required from both the Florida Department of Transportation and the South Florida Water Management District. It was necessary to meet all requirements for these agencies and for the Miami-Dade Water and Sewer Department (MDWASD). The old pipe remains in use and this increases the capacity to almost three times that available originally.

Another project was the design of two 350 gpm pumping stations meeting MDWASD standards. Also included was 2.5 miles of 12 inch diameter force main that connected to an existing force main. Because MDWASD did not have capacity for the project, a study was completed. The study revealed that capacity was available with an improvement that was remote from the site. MDWASD did the engineering and construction with the client paying for the improvement.

For a client in Hialeah, Leiter, Perez & Associates, Inc. designed two flooded-suction pumping stations to serve over 600 acres. Stations were 600 gpm and 700 gpm and both were equipped with permanent, on-site diesel generator sets. A 12 inch force main 1.5 miles long with one aerial canal crossing completed the project. This force main was connected to the N-11 interceptor force main.

Leiter, Perez & Associates, Inc. was retained to develop a utilities master plan for a nearly 1,300 acre site in west Dade. The plan included three pumping stations, one being considered a "regional" station of 2,000 gpm capacity. Permanent hoisting equipment and an on-site generator set were included in this facility. The other stations were each 700 gpm and all were of the flooded-suction type. Off site improvements for the site included 3.5 miles of 24 inch diameter water main and the same length of 16 inch diameter force main. Two aerial crossings and two jacked and bored railroad crossings were required for each pipe. This project provides services to the "Free Trade Zone" and the International Mall in west Dade County.

A large development in Pembroke Pines required two sets of contract documents when the city refused to share in the oversizing costs. Originally, the project was to serve two square miles of the Pines, but the area served was reduced to 800 acres when the city declined to participate. Originally, the master pumping station was to be 3,500 gpm with an auxiliary generator set, but redesign reduced it to 2,000 gpm. Only the pumping station, 20 inch force main, and 4,000 feet of gravity sewer were affected by the redesign, with the other stations and force mains remaining the same. Water mains, located along the through streets in the area did not change in size. They amounted to 1 mile of 20 inch diameter, 2 miles of 16 inch diameter, 2-1/2 miles of 12 inch diameter, 2 miles of 10 inch diameter and 1/4 mile of 8 inch diameter. The project was delayed by an economic downturn and when it was revived, the City took the project over and had it built as originally designed.

A 20 inch diameter water main was designed to serve a development along the Intracoastal Waterway in Northeast Dade County. The project included a subaqueous crossing of the Ojus Canal and permits were required from the U. S. Coast Guard, U.S. Corps of Engineers, Florida Department of Natural Resources, FDER, and Dade County as well as the City of North Miami Beach, who required the main be put in. All permits were obtained in a very short time and construction was completed promptly.

Consulting services were and are being provided for the development of Fisher Island. This is a large residential complex and marina on an island south of and adjacent to the Port of Miami ship Channel. Surveying and engineering work consisted of all aspects of work done in the field, including roadway locations, water distribution and sewage collection systems, and full on site drainage detention. Stormwater drainage is disposed of using deep wells with some overflow to the on-site lake during extended periods of rain. Emergency overflow to Norris Cut and the ocean provide for periods of unusual atmospheric disturbances. Additional work included site and street grading, grading of building sites, digging of two lakes, and establishment of an astronomical observatory. Included in the original site development was an 85 acre area set aside to be developed as a golf course. The site includes the small lakes mentioned earlier, water features, a clubhouse, putting greens and a driving range. Permits were required from FDER and the Dade County Water Control Division. Additionally, a class II permit was required for the overflow into the lakes. The entire course project was "fast-tracked," with design, permitting and construction being completed in a 15 month period. This course is now the home of the "Merrill-Lynch Shootout," which is being added to the PGA circuit. The first "Shootout" was held on October 22, 1991.

Leiter, Perez & Associates, Inc. provided all aspects of civil engineering services for the Doral Villages at Miami, adjacent to the Doral Country Club. Work included grading, drainage, paving and a combination bridge-culvert crossing. Drainage consisted of full on-site retention with stormwater disposed of in large French drains. Site access was accomplished via a bridge-culvert structure designed around the theme of the project, a Venetian canal setting, with the roadway crossing an existing lake. The site was provided with curb and gutter.

Consulting services are being provided for the Oceania Project at 163rd Street and Collins Avenue, on the ocean. Before start of construction, the coastal construction line had to be established along with the mean high water line. Leiter, Perez & Associates, Inc. also did the layout for the water distribution and sewage collection systems and drainage, including a rainwater pumping station. Drainage is designed for a 100 year storm because of the proximity to State Road A1A, (Collins Avenue), and all run-off to be disposed of on site. A combination of deep wells and French drains are used to take care of the storm water. Rainwater draining into the garages under the buildings is provided for with shallow drainage trenches, overflow being handled by the pumping station mentioned earlier. This station discharges directly into the deep well system. Site access is via a driveway connection to Collins Avenue (A1A), with curb and gutter and sidewalk provided. The utilities layout for the site was also established, including telephone, security, power, and cable TV. Pile locations for all buildings have been provided, with final driven locations checked using information transmitted from the field to an office computer. Variations from staked positions are noted and checked to see that piling can be used.

Other projects include one with 2.5 miles of 20 inch diameter force main and 4 pumping stations and another with 6 stations and several miles large force main. Both projects also included several miles of water main in sizes from 24 inch diameter to 36 inch diameter.

Presently, the surveying department is working on projects throughout Dade, Broward and Palm Beach Counties. The field work involves boundary and topographic surveys, hydrographic surveys, mean high water surveys and section surveys. Also included are construction layout as mentioned above, "as-builts" of underground utilities in private and public roadways, layout for construction of public and private roadways in subdivision work, including subgrade, base rock and finished pavement. Condominium surveys, special purpose surveys, volume surveys and tree location surveys also are part of the work, along with building layout and piling layouts as previously mentioned.

Office work includes land planning and subdivision design drawings, all land survey related drawings, and sketches of easements and legal descriptions for utilities locations.

Calculations of excavation and fill volumes, preparation of plan and profile drawings and cross sections, and geometrical drawings showing construction layout of proposed improvements are also prepared.

Support of the type described above has been and is being provided at Fisher Island in Miami Beach, The Pointe, The Millenium and Oceania in North Miami Beach, and Swire Properties on Brickell Key in downtown area of the City of Miami. Fisher Island includes numerous high rise structures requiring piling as does the three thirty story buildings being built at Oceania. The Pointe, The Millennium, and Brickell Key.

Several shopping centers have been provided surveying services in the last several years. The Garden Square Center included a boundary and topographic survey with muck probings to determine the limits of unsuitable subsurface material. At the Westchester Shopping center, a boundary and topographic survey was provided at an existing center for renovation. An off-site route survey was provided for a one-half mile water main extension. Construction layout and "as-builts" were provided for the underground utility construction. More recently Leiter, Perez & Associates, Inc. has prepared a complete survey of the Dadeland Mall in South Miami and the Westland Mall in Hialeah, FL.

Leiter, Perez & Associates, Inc. has provided surveying services for BellSouth Mobility which has included site surveys for locations of antennas, parcel surveys, legal descriptions, and GPS data.

Some of the environmental land survey jobs consist of pile construction layout and as-builts of a lead contaminated site near Jackson Memorial Hospital, Dade County and a topographic site survey to identify runoff and containment problem at N.W. 21st Street in Miami, FL.

The firm has provided civil engineering and surveying services to Home Depot in Dade, Broward, Palm Beach and Charlotte Counties. Services provided included boundary and topographic surveys, legal descriptions, and easements. Civil engineering work included water distribution and sewage collection system designs and drainage and pavement design.

For Dadeland Mall, an engineering study and route survey were provided for a force main extension to increase capacity. Right-of-Way involved was a drainage canal and permits were obtained from all agencies involved.

Surveying work was provided to a contractor constructing a land fill for Broward County. A geometric evaluation of the site was prepared including the establishment of originally proposed location of various sectors of the site. The cut and fill volumes for percentage of earthwork completed was also prepared.

Other developments in which the surveying department had a major role were the Doral Estate Villas, Westpointe Apartments, Royal Palm Place at the Hammocks, Pines Pointe and Bayshore villas. Several of these projects were townhouse condominium developments and required preparation of Condominium Surveys for the individual units as well as the routine boundary and topographic surveys, muck probings, platting, land planning and subdivision design. All of these projects required construction layout and "as-builts" of the drainage and utilities,and building layouts. Also required in many cases were foundation surveys, and construction layout and "as-builts" of public road improvements.
